Description: Generators are machines that help to transform mechanical electricity using the Faraday law of magnetic induction. According to the Faraday's law, when a conductor is placed in a varying magnetic field, an electric magnetic field is induced. The most important elements in a generator are the magnetic field and motion of a conductor in the magnetic field. The generators are designed using coils of electric conductors that are tightly wound on a metal core. The coils turn inside an exhibit or magnets to induce flow or electric current inside. The conductor coils and the core are referred to as an armature that connects to the main shaft of a mechanical power source. The main types of power generators include AC generators. These generators are designed to generate alternating current because many home appliances use AC current as opposed to direct current. The generators operate using the principle of magnetic induction. You can opt for the induction generator that does not require separate DC excision. This model is used in offices and homes. However, for larger facilities that require high AC power generation, the better option is the asynchronous generator that takes current via slip rings and bushes. The main advantage of AC generators is that they are easy to maintain, the sizes are relatively smaller, and do not break down easily.DC generators: These generators are found in off-grid applications. The generators provide a seamless power supply to the electric storage units. These generators can be classified depending on the way their magnetic fields are developed. The main types of the DC generators are the permanent magnetic DC generators, separately-excited DC generators, and self-excited DC generators. The main advantages of DC generators are that the output voltage is smooth and the DC machines have wide-ranging operational characteristics that can be obtained through the selection of the field windings.
